Buying links isn't soo bad, as we hear everywhere!
Google, like most search engines, use links to determine a website's relevance and authority. A website's ranking on Google search results is based on many factors, including the quality of websites that link to it. Link based rating has greatly improved Google's ability to return relevant results in a search.
If you buy good high quality relevant link, it only helps your site!
We are not talking here about some suspicious resources, we are talking for some grey seo for better ranking.
